Early application value of pulmonary ultrasound combined with arterial blood gas analysis in emergency patients with multiple severe injuries complicated by respiratory failure

Abstract

OBJECTIVE: To study the early application value of pulmonary ultrasound combined with arterial blood gas analysis in emergency patients with multiple severe injuries complicated by respiratory failure.METHODS: Eighty-one patients with multiple severe injuries complicated by respiratory failure treated in the intensive care unit of the emergency department of our hospital between January 2020 and January 2021 were retrospectively analyzed. According to the different examination methods, the patients were divided into three groups (n = 21), diagnosed only using pulmonary ultrasound (group A), diagnosed only using arterial blood gas analysis (group B), and diagnosed using pulmonary ultrasound combined with arterial blood gas analysis (group C). The initial diagnosis time, diagnosis time, and correct treatment time for patients in each group were recorded. The diagnostic rates of bedside pulmonary ultrasound, blood gas analysis, and bedside pulmonary ultrasound combined with blood gas analysis were compared. Patients were divided into a survival group (n = 65) and a death group (n = 16), and the predictive effect of pulmonary ultrasound on the long-term prognosis of patients was analyzed.RESULTS: The initial diagnosis, diagnosis, and initial correct treatment times in groups B and C were significantly shorter than those in group A, and the initial diagnosis time, diagnosis time, and initial correct treatment time in group C were significantly shorter than those in group B (P < 0.05). The diagnosis rate of the examination method in group A was significantly lower than that in groups B and C (P< 0.05). The lung ultrasound (LUS) score in the survival group was significantly lower than that in the death group, while the right diaphragm displacement, left diaphragm displacement, and average diaphragm displacement in the survival group was significantly higher than those in the control group (P < 0.05). The LUS score in the survival group was significantly lower than that in the death group, while the right diaphragm displacement, left diaphragm displacement, and average diaphragm displacement in the survival group was significantly higher than those in the control group (P<0.05). The receiver operating characteristic curve results showed that right diaphragm displacement, left diaphragm displacement, and average diaphragm displacement had good predictive value.CONCLUSION: Pulmonary ultrasound combined with arterial blood gas analysis is of significant value in the early assessment of patients with multiple severe injuries complicated by respiratory failure and has important clinical significance in the timely treatment and prediction of patient prognosis.
